FRUIT-JAR covEn;

To all whom it may concern.-

. Be itknown thatl, CHARLES citizen of the United-States,- residing at Manchester, in the, countyhof Hillsborouglr and State of New Hampshire, have in, vented certain new and useful Improvements in Fruit+Jar Covers, of which they is a specification, reference being following had to t e accompanying drawing a This invention relates to an improved;

fruit jar closure and-Qclam therefor, and

an object of the invention is to provide a I closure, which is simple, efficient and practical in construction, and maybe manufac; cost and sold at a.

- I eyes to be engaged by-the hooks of the,

around t eneck of; the jar, and an arched of: the, I closure and provided with detach'a e hook;

metallic strap arching acrossthe toip 1 connections. with the anchoring. ring, anda screw threaded through the strap andcontactin witha part of, the top of the closure, wherey it may-be forced tightly in posi-; tion, there being a gasket carr'ied byythe' closure engaging the marginal edge of, the, openend of; the jar,,soas to seal thejar. tight, when the closure, is' clamped in posi-,;

. The seas-.1; further ass a provide mean nwa part of the, closure to be enev gaged by theiend of thescrew-, toprevent i lateral displacement thereof. l M U5;

The inventionfurther aimsito provide olfhe d le ook conlle ctions-spaced f the neck.,';

.While the design and construction at, present illustrated andsetiorth isdeemed prefferable, it is obvious that asa result of a reductionoftheinvention to a niore practi-' cal-form for commercial purposes the. in-

ventionmay besusceptibleito changes, and the right .to ;these changes is clalmeds Pm ,The invention further aims to provide an 1 anchoring. ring having diametricallyoppo- 5 site eyes, to receive hooked ends of; a twisted wire clamping. I member," which arches fithe closure, and'which-also carriesa clampingscope of what; is claimed. V

The invention comprises further features and co nbination of parts, aswill be herematter set forth, shown in the drawings and claimed. V

ring, showing the diametrically opposite arched clamping member. 7

Fig. e is'a sectional, view through the up Fig" 5 is. a de tail perspective view of the anchoring ring to be engagedby the clamping'. strap- .1

Fig, 6 isv a detailperspectiye view of the clamping. strap.

Referring more especially to the drawings, 7 1 designatesthe body of a fruit jar, havinganeck 2, and 3 denotes a closure,-which of a. general .shapeasshown, but may be otherwise constructed, and is provided with an annular groove or channel 4,, for the re-' ception of the gasket or washer 5, whichmay be constructe of any suitable, material,

referably rubber or a ,composition'of, rub- 3 er and canvas. This gasket or washeris; designedto engagethe upper marginal edge 7 of the-open end ofithe jar, to insure a fluid and air-tight seal between the closureand the jar.

Anv anchoring ring 6 is in surrounding-Ye lationto the neck of the jar, and thisvjring is constructed from a single length of .wire

595 having its. ends providedwith intren'gaging hooks 7, to "hold the ring in place ongthe neck. This ring is bent at diametrically op posite portions, to form eyes 8. z A. clamping .7

arch member 9 is provided. This, clamping.

arch member-is constructed fromasingleI I length of wire, which is twisted upon itselfas illustrated,.to"insure1strength and rigidity. However, when thewire of thecl ampe- 1 closure to-be moved laterally.

words, before loosening the screw, the open.

ing arch is twisted together, the opposite portions of the wire substantially centrally of the arch arebowedoutwardly, as: shown at 10, thereby providingan open1ng. l1, which is threaded to receive the binding or clamping screw 12, The end portions of the clamping arch are bent toforin hooks 13,

which engage the diametrically opposite eyes of the anchoring ring. WVhen closing the jar, the closure is applied in position, then the clamping arch is moved to arch the closure, after which the binding. screw is adjusted, so that its extremity will engage a transverse groove '14 of an enlargement 1'5, which forms an integralpartof the npper' face of the'closure The closure 18 designed to be positioned, so that the transverse groove 14 is disposed in a plane-parallel with the transverse disposition of the clamping arch, so as to prevent the clamping arch from swinging laterally, and consequently prevent the extremity of the screw 'from' disengaging the" groove of the enlargement I When the extremity-of the.

of the closure. screw is in contact with the transverse grooveof the enlargement, the screw ist'ight ened, thereby forcing the closure tightly into position; in order to insure a seal between the gasket or washer and the marginaledge of the open end of the jar. The groovefl not only prevents the clampingarch from swinging laterally, but also permitstthe ator may apply pressure on the side of'tlie closure,'soas to rupture the connection or contact between the upper marginal-edges of the j ar opening and the gasket or washer 5, so that when the screw isloo'sened, the

closure may be more readily removed from thejar. Furthermore, pressure maybe-a1) r plied upon the clamping arch,-ma -direction with the arch, that-is longitudinally with stated.

I11 Figs. 4, 5' and 6, the anchoring rin'gy insteadof having the eyes, is provided with diametrically opposite offset parts 16, which areen'gaged by the hooks 17 of the arched metallic strap 18. This metallicstrap. is more or less flexible, andits 'central portion receives a threaded j shank I of 1a clamping screw 19'. In applyingthe closure- 1 shown in Figs. 4, 5 and 6, the closure is placed in position, their one end of the me tall-ic' strap is formed into*-the =hook, and

In 1 other placed in engagement with one of the oflset portions of the anchoring ring. The other end of the strap is then inserted through the-opposite offset portion, and bent lupwardly as shown to provide the other hook on the strap. ,The clamping screw is then tight'ei'ied, with its'end'firmly engaging the groove and the enlargement of the upper face of the closure, and by tightening up the screw, and tensioning the strap, the closure will be forced into positlon to insure a fluidnndxairetightuseal with the marginal edge of the upper open end of the jar, through the medium'of the gasket orwasher. When the screwis loosened and th'e clamping arch member or wire9 is removed, the cover can: be easily taken-off: without the useof a knife ora'ny other sharp instrument in between'the closure and the 'marginal edge of the=jar, or withoutsubmerging the jar into hot water-,for the purp'oseof softening the seal or the :j oint between the closure and the The invention having been set forth, what isclaimed as new and useful is 1.
